(4131. 2449-42) ABSTRACT OF THE DISCLUSURE This invention relates to improvements in television lamps and, more particularly, to a type of lamp which on being attached to the rear wall of a television set and lighted will brighten up the surroundings therebchind.

The principal object of the present invention is to provide an extensible lamp for attachment to the perforated rear ventilation Wall usually found on a television set, including a plurality of spring-urged telescopable tubular elements provided at their ofistanding end portions with receptacles which are adapted to contain illuminable lamps as well as reflector means which are positioned adjacent thereto, thereby furnishing an increased amount of illumination.

Another object of the invention is to provide longitudinally aligned hook means on each of the telescopable elements which facilitate assembly of the television lamps with the perforations in the rear wall of the television set.

Still another object of the invention includes means for holding the telescopable elements in substantially abutted relation thereby reducing the length of the lamp for shipment or storage.

A further obiect of the invention is to provide in adjustable reflecting means which includes guide or stop means adapted to cooperate with the contour of the bulb and to prevent complete withdrawal thereof when a bulb is positioned in the sockets of the receptacle.

A still further object of the invention is to provide multiple switch control means for manual actuation of the television lamp as well as automatic switch means therefor which are under the control of the television set.

Other objects and advantages of the invention will be hereinafter described or will become apparent to those skilled in the art and the novel features of the invention will be defined in the appended claims.

In the accompanying drawings:

FIG. 1 is a side elevational view of the improved television lamp in its shortened form for storage or shipmcnt;

FIG. 2 is also a side elevational view of the television lamp shown in FIG. 1 and in which the telescopable elements have been elongated preparatory to attachment thereof to a television set;

FIG. 3 is a cross-sectional view on line 3-3 of FIG. 2;

FIG. 4 is a cross-sectional view on line 4-4 of FIG. 2;

FIG. 5 is a side elevational view generally similar to the device shown in FIG. 1 and in which a diiferent type of spring is used;

FIG. 6 is also a side elevational view of the device shown in FIG. 5 and in which the spring is of the type States Farm 0 which elongates the telescopable elements preparatory for attachment to a television set;

FIG. 7 is a fragmentary perspective view of one telescopable element showing the removable reflector means;

FIG. 8 is a front .elevational view showing a modified form of the television lamp adapted for attachment to the television set;

FIG. 9 shows one circuit layout for automatically illuminating the television lamp when the television set is turned on; and

FIG. 10 is another circuit layout including a thermorelay which prevents the television lamp from being illuminated until the television set becomes warm.

Turning now to the drawings there is shown in FIG. 1 a side elevational view of the new television lamp denoted generally at 10 which includes a pair of slidably arranged telescopable elements 12 and 14 which are retained in abutted shortened relation for shipping or storage by means of the tension spring 16, the free ends of each of which are fastened to pins 18 and 20 carried by each of the telescopable elements. The entire device is electrically wired and ready for use and included at the diametrically opposed end of the television lamp element are lamp receptacles 22 and 24 which are equipped with bulbs 26 and 28 and suitable reflective means 30 and 32 which are shown as elongated portions that extend beyond the back wall of the television lamp 10. These reflector means may be integrally formed as a part of the television lamp or slidably mounted in guide means as will be described hereinafter in greater detail.

It is to be understood that although as shown in the figures in the drawings and best shown in FIG. 3, the crosssectional area of these telescopable elements is substantially square, they may assume any other suitable substantially tubular configuration.

A manually operated switch means 34, which is included for the purpose of illuminating the television lamp when desirable, is provided, although, as will be pointed out later herein, this type of switch is not necessary since the television lamp can be connected into the circuitry of the television set to which it is attached and thus lighted when the set is turned on.

The view of the device shown in FIG. 2 differs from that in FIG. 1 only in that the spring 16 is shown extended and with the telescopable elements of the lamp moved longitudinally of each other preparatory to fastening the television lamp to the preforated back panel (not shown) of the television set by means of suitable hooks which may take the form of struck-out tongues 3636 or any other suitable configuration.

In FIG. 3 there is shown a cross-sectional view through the lower telescopable element on line 3-3 of FIG. 2 clearly illustrating the manner of slidably associating the telescopable elements, each of which includes guide means extending longitudinally of their inner rear walls and wherein the telescoping element 12, which encompasses telescopable element 14, includes inturned flange means Fad-38 into which longitudinally extending tongues 4ti4ti extend thereby facilitating guidance of the respective elements as they are moved relative to each other.

FIG. 4- is a sectional view on line 44 of FIG. 2 showing a stop pin 42 carried by the rear wall of telescopable element 12 which is adapted to cooperate with the elongated slot means 44 provided in the rear wall of telescopable element 14. It is to be noted that the slot 44 terminates above the lower extremity of telescopable element 14, as at S, thereby preventing inadvertent separation of the respective elements when they are pulled apart preparatory to assembly of the device with the television set.

In a further embodiment of the invention shown in FIG. 5, it will be noted that the overall design and construction of the television lamp generally approximates that shown in FIG. 1 except that in this instance each of the telescopable elements 12 and 14' are provided with an inwardly projecting ledge 16' and 18' respectively, each of which is adapted to support diametrically opposed sleeve-like members 2% and 22, respectively. The sleeves 20 and 22 confine a compression spring 24 which, when the pin-like means 26 is removed from the aperture provided in telescopable element 14', will cause the inner telescopable element 12' to be extended into a position such as that shown in FIG. 6, at which time the prongs or hook-like means 28'-28 may be inserted into the perforations provided in the rear wall of the television set.

In FIG. 7 there is shown a fragmentary perspective view of still a further modified form of the invention in which the means taught therein are adaptable to either of the forms of the invention described in connection with FIGS. 1-2 and 5-6.

For purposes of a clear understanding of this embodiment of the invention a fragmentary portion of telescop able element 12 is shown. As distinguished from the other embodiments of the invention previously referred to and in lieu of having a fixed or immovable reflective means of the type shown at 30 and 32 in FIG. 1, it is contemplated that there be included herein a rigid longitudinally extending hose or support member formed as a part of the rear wall of the lamp 10 which is provided with diametrically opposed internal flanged portions 52--52 which permit slidable movement therebetween of the reflective element 54.

Offstanding from the inner surface of the reflective medium 54 which may comprise a polished metal plate, is a stop means 55 that is secured to said plate in any suitable manner the right angularly extending wing-like portion of which may be adapted to conform to the exterior configuration either of the socket of the lamp or its glass envelope.

As shown at 5656 the flanged portions 52-52 are depressed toward the hose member 50 to thus provide a frictional gripping means on the reflector 54 to thereby prevent its being inadvertently detached from its support when e.g. it is shipped without the benefit of a lamp being provided in the socket.

In FIG. 8 there is provided at 6% a connection for the current supply cable 62 for the television lamp and the television set.

As described hereinbefore 34 is the button of the onswitch of the television lamp and at 64 a connection is provided for a plug 66 which is carried by the television set. On the instrument, according to FIGS. 8 and 9, the plug 64 of the television lamp is fixed into the socket of the set. The television set is then operated by push button 34 by virtue of the leads 68 connecting the supply circuit 62 for the lamp to the power circuit of the television set.

In FIG. 10 there is shown a thermo-relay 70 connected in one of the leads 68. With this arrangement synchronous on and off switching is effected for both the lamp and the television set. Thus, when the television set is turned on in the conventional manner, a slight voltage drop occurs across the thermo-relay which passes the required amount of current to operate switch 72 only after a preselected period of time corresponding to the warm-up time of the television set. Accordingly with such a circuit arrangement a satisfactory operation of the television set is effected wherein on and off switching of the lamp is synchronous with the on and off switching of the television set,
